Advanced Formation Evaluation

Program Objectives

This comprehensive advanced course is designed to provide solid understanding of the most commonly used open-hole logs and Core analysis techniques. Participants will gain the foundation, experience and techniques to read and interpret each log for evaluating reservoir parameters such as lithology, porosity and saturation. Participants will learn how to analyze a log suite and come up with interpretation and suggestions through extensive exercises and team work. Throughout the course, instructor(s) will encourage students to perform hands-on calculations of petrophysical properties using illustrative examples. Participants will learn:
  • Core analysis techniques and significance of measured properties 
  • Introduction to logging and geologic understanding through well logs 
  • Drill Stem testing fundamentals 
  • Objectives and principles of production logging and formation testing 
  • Advanced log analysis techniques for complex reservoirs 
  • Shale gas analysis techniques
